The second British scientist related to CERN’s origination back in 1952 is Peter Ware Higgs who contributed to our understanding of subatomic particles:
Peter Ware Higgs CH FRS FRSE (born 29 May 1929) is a British theoretical physicist, emeritus professor at the University of Edinburgh, and Nobel Prize laureate “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles”.
The background on Peter Higgs is that he is best known for the Higgs boson (the “God particle”), an elementary particle in the Standard Model of particle physics.
This so-called Higgs mechanism, which was proposed by several physicists besides Higgs at about the same time, predicts the existence of a new particle, the Higgs boson, the detection of which became one of the great goals of physics. CERN announced on 4 July 2012 that they had experimentally established the existence of a Higgs-like boson, but that further work would be needed to analyse its properties and see whether it had the properties expected from the Standard Model Higgs boson.
